##### Solve -1^2 + (-1)^ 2 =...? ________________________________

```        0
```
##### Explanation
```       2
Here -1  mean exponent 2 is only at 1
and negative sign is without exponent.

Let we have a polynomial

3   2
= x - x + 3x + 5

2
Here look at -x
```

The exponent is only at x and negative is sign is without exponent. During solution of above polynomial we never convert it toward to positve x^2.

```Similarly for further explanation

2
= 5x + 14x + 2

2
Here again focus on 25x .
```

The exponent is only at x and the co-efficient 7 is without exponent. During solution of above polynomial we never convert 5x^2 to 25x^2 and we can convert 25x^2 if (5x)^2 is given.

We should also understand that the order of operation (BODMAS) is the key of mathematics. and negative sign is take as multiplication so the exponent should be solve before the multiplication

```Solution :
2          2         2
-1  mean -(1)   and (-1) mean (-1 × -1)

2       2
-1  + (-1)

= -(1.1)  + (-1 × -1)

= -1  + 1

= 0
```
